Uvod u RFID kartice
In today’s fast-paced and data-driven business world, the need for efficient tracking, contactless access, and real-time inventory management has never been greater.
RFID kartice—powered by Radio Frequency Identification technology—are becoming game-changers in industries such as retail, logistics, healthcare, and security.
But what exactly are RFID cards, and why are they so valuable? Let’s explore how RFID cards deliver significant business advantages in access control, supply chain efficiency, and asset tracking.
What Is RFID and How Do RFID Cards Work?
RFID stands for Radio Frequency Identification, a technology that enables data transmission between a tag (or transponder) and a reader using radio waves. This allows for wireless identification, authentication, and data exchange without direct contact or line-of-sight—making RFID incredibly powerful for automation and tracking.
The Basics of RFID Technology
At its core, an RFID system consists of three main components:
1. RFID Tag/Card (Transponder):
This contains a microchip for data storage and an antenna to receive and transmit signals.
2.RFID čitač (Interrogator):
A device that emits a radio signal to detect nearby tags, receive their data, and send it to a computer or software system.
3. Backend Software System:
Integrates with the reader to process, store, and analyze the collected tag data (e.g., access logs, inventory movements).
Vrste RFID oznaka
There are three frequency bands commonly used in RFID:
| Frekvencijski pojas | Opis | Typical Use Cases |
|---|---|---|
| LF (niska frekvencija) 125–134 kHz | Mali raspon čitanja (do 10 cm) Good through metal/liquid | Livestock tracking, access control |
| HF (visoka frekvencija) 13,56 MHz | Medium range (up to 10 cm) Often NFC compatible | Smart cards, event tickets, library systems |
| UHF (Ultra High Frequency) 860–960 MHz | Long read range (up to 10+ meters) Fast read rate | Logistics, warehouse inventory, retail tag |
Most RFID cards operate at 13.56 MHz (HF) and comply with the ISO14443A standard. This standard is commonly used for access control, NFC, and tap-to-pay systems.
Active vs. Passive RFID Cards
- Passive RFID Cards:
These cards have no internal battery. The signal from the reader powers them, and they are most common in access control, ID systems, and NFC tags. - Active RFID Cards:
They contain a battery, allowing them to transmit signals over longer distances and store more data. They are typically used in high-value asset tracking or real-time location systems (RTLS).
Business RFID cards are almost always passive, cost-effective, and maintenance-free.
How RFID Cards Transmit Data
Here’s how a typical RFID card works step-by-step:
1. The reader emits a radio frequency field.
2. When the card enters this field, its antenna picks up the signal.
3. The chip inside the card powers up (if passive) and responds by sending its stored data (such as a unique ID).
4. The reader receives and passes the data to a software system.
5. Based on the tag’s data, the system grants access, logs an entry, updates inventory, or initiates another process.
All this happens in milliseconds—with no physical contact required.
RFID Cards vs NFC Cards – What’s the Difference?
NFC (Near Field Communication) is a subset of RFID technology, based on 13.56 MHz HF RFID. But there are some distinctions:
| Značajka | RFID kartica | NFC Card |
| Komunikacija | One-way (reader to tag) | Two-way (tag and device communicate) |
| Kompatibilnost | Requires RFID reader | Compatible with most smartphones |
| Raspon | Do 10 cm | Up to 4 cm (shorter, but more secure) |
| Slučaj upotrebe | Access control, ID, inventory | Mobile payments, smart posters, pairing |
NFC RFID cards are ideal for applications involving smartphones or consumer interaction.
Common Formats of RFID Cards
